Git, Visualized to the Metal — Episode 1: The Three States (Working, Staging, Repo)
Most Git tutorials show you commands. This series shows you the data
structures Git is mutating on disk.
Episode 1 — The Three States. Before you can understand branches,
merges, or rebase, you have to see the three places a file can live:
the Working Directory, the Staging Area, and the Local Repository.
We walk through what each one actually is, why Git was designed this
way, and we open up the .git folder to see it on disk.
What you'll learn:
The three local states of Git, by color (Red, Yellow, Green)
What's actually inside the .git/ folder
Why staging exists — and why two states would not be enough
How one file moves from Working → Staging → Repo
What's hiding inside .git/objects/ (we open it in Episode 2)
This is Episode 1 of an ongoing series. Subscribe so you don't miss
the next episode — we crack open the object database and see exactly
how Git stores every version of every file you have ever committed.
